Narrative:

Upon taking runway 25R the right engine would not spool up. After several attempts the right engine appeared to respond and the takeoff was initiated. At 80 knots I felt things were settling to normal and we could continue the takeoff. I was then out side and prior to V1 the first officer called abort. The abort was several knots bellow V1. The right engine was erratic again and that is why we aborted. The abort was normal with no further incident.do not continue a takeoff above 80 knots if either engine is not within parameters.

Title: An MD-83's right engine stabilized at takeoff thrust after being slow to spool; but at about 120 KTS its EPR began oscillating so the Captain rejected the takeoff.
